Certain vendors have shipping restrictions that require us to collect a handling fee for the part. You'll see it on the item page as a Vendor Handling fee, and it will show up in the cart below the item(s) you're ordering.

There are more than two hundred moving parts in the average gas-powered engine, most of which would cause problems if they failed. Because it is so large and it includes so many components, engine repairs can cost a pretty a penny. Not only do you have to find out what the problem is, you also have to get to the damaged parted, which may require removing dozens of other parts. If you hear a knocking, clunking, or squealing sound emanating from under your hood, stop driving immediately. Since most of these components are connected, a damaged part can damage those it is connected to. We offer a wide array of Jeep TJ internal engine components for replacement or upgrade.

Word On The Trail

Never had anything but the best on line experience with Extreme Terrain.com. Prices are always competitive. I have spoken with customer service and they have been very helpful and friendly. Shipping is always fast and has been free on items over $75. I will use them for all of my Jeep needs.
